ROTARY ENGINE. I

Specification of Letters Patent.

Application filed April 9,1906. Serial No. 310.706.

To all whom it may concern:

Be it known that 'I, CONSTANTINE DEMEIRIUS MA- oRoPoULos, a subject of the King of Greece, residing at 28 Clarendon road, in the county of London, in England, gentleman, have invented a new and useful RotaryEngine of the Impact-Wheel Type, of which the following is a specification.

' the shaft d fixed to the wheel.

My invention relates to rotary engines. Figure 1, is an isometrical view of the rotary engine with a part of the cylinder casing a cut away in order to show the interior revolving wheel b which travels with the shaft d inthe direction indicated by the arrow. Fig. 1 shows the wheel b in one piece of metal, with Fig. 2 is a transverse section of Fig. 1, showing a part of the wheel I) with one of the chambers 12 being placed opposite the steam port f; and the exhaust-port g. V

This invention consists of a solid or massive wheel 1/, mounted ona shaft in a case or cylinder (1 and covers 1; in the outer circumference of the wheel b there are opened any number of chambers e, ol a uniform size, at an equal distance from one another. They are arranged in a row and take an inward oblique direction i. c. deviating from the center. The wheel I), so made is mounted on the shaf t d, and can be driven either by steam, gas, compressed air, or water under pressure.

The wheel may be of any size, large or smalh There are rows ofchambers a, and the size, and. number of the chambers a may also vary.

The wheel l/ fits exactly in the cylinder or casing a, touching the walls of it to such an extent, so as to be free to rotate.' The cylinder a is closed at both ends by a cover q, leaving only the necessary openings for the shaft of the wheel to go through. In a certain part of the circumference of the cylinder there are two or' more steam-ports f, through which the steam passes into the chambers, and pushes the wheel b'-cr using it to rotate. These are the admissionsteam portsy and I they are placed in such a manner that the steam fills.

the chambers e of the wheel b, one of eachrow 'alternately, thus forcing it to continually rotate. The admission of the steam may also be done by any number of steam-ports. Also in the circumferenceot the c'ylinj'i-i dricalcasing at a regulated distance from-the admission port s, there is an exhaust-port g by which .the

steam escapes, when the chambers arrive at this-point I while rotating.

I am aware that engines of the impaQt wheel ty-pe have been used before, and I do not clainrsuch as my;

invention, but I am not aware that engines with a wheel b of any size with more than two rows of chambers e,

as illustrated and described inmy specification "have ever been used before, and therefore I claim this as my invention The pockets or chambers e, are arrangedat an angle,

are elongated intho direction of th'eaxis of-the wheel,

and have shallow branches of less width than the pooh:

ets.

have passed the steam port f. This prolonged supply These branches are provided to keep up a supply v to the pockets after the main portions of the pockets 7 is maintained on account of the initial condensation taking place on the entrance of steam into the main portions of the pockets.

' What I claim, and desire to secure ofthe United States, is-

port and an exhaust port,'of a wheeltig'htly fitting within said cylinder andprovided with pockets having shallow.

ln-uuchcsot less width than the pockets.

In tosthnonywhereof I have signed my name to this by Letters Patent The combination with a cylinder provided with a steam specification in the presence of two subscribing witnesses.
